Your entire system may be loosely built, you say that unplugging your power code loosened the ram somehow and you are receiving electric shocks... right? Those shocks, I get them whenever the earth pin isn't properly making electrical contact with the metal case be it the fridge or any appliance that uses a 3 pin plug. If you have a mult-tester/meter unplug the power code ones again, locate the earth pin on your plug, set your multi-meter to continuity test mode, put one pin of the multi-meter on the metal chassis of your casing and the other on the earth pin of the power code of the PSU plug. It should register continuity. If it doesn't register then there is your shock problem source. There should be continuity indicated by a meter reading or continuity noise from the multi-meter to indicate electrical connectivity.

You also need to check all other parts thoroughly of your PC for firmness, your rams weren't firmly fastened and maybe it also may apply to other components too. How are your temps?
